Essence sans odeur

Essence minerale inodore

L'essence minérale inodore: Cette essence , qui offre des mises en solution proches de l'essence de térébenthine, a l'avantage d'être inodore et ne présente aucun risque d'irritations ou d'allergies.

Elle est particulièrement recommandée pour les personnes travaillant dans une pièce fermée.

Purpose: Reducing consistency of oil colour, cleaning materials
Composition: Mineral oil distillate with minimum possible content of harmful constituents
Odourless; drying time somewhat longer than white spirit
Makes the bottom coats lean (thinner); only to be used for the first coats
Not suitable for removing dry varnish coats

Artists use mineral spirits as an alternative to turpentine, one that is both less flammable and less toxic. Because of interactions with pigments, artists require a higher grade of mineral spirits than many industrial users, including the complete absence of residual sulfur. Odorless Mineral Spirits are mineral spirits that have been further refined to remove the more toxic aromatic compounds, and are recommended for applications such as oil painting, where humans have close contact with the solvent.

In screen printing (also referred to as silk-screening), mineral spirits are often used to clean and unclog screens after printing with oil-based textile and plastisol inks.

A typical composition for mineral spirits is the following: aliphatic solvent hexane having a maximum aromatic hydrocarbon content of 0.1% by volume, a kauri-butanol value of 29, an initial boiling point of 149 °F (65 °C), a dry point of approximately 156 °F (69 °C), and a specific mass of 0.7 g/cc.

Non-toxic Solvents

Paint companies do not ?invent? odourless solvents: they have been around for many years and are supplied by the major oil companies. They are petrochemicals, with the toxic aromatic (smelly) fractions removed, making them much less toxic than gum turpentine, mineral turpentine, or white spirit.

Odourless solvents are much slower evaporating than turpentines, so that very little vapour is generated during a painting session, and this factor is more important than the lower toxicity itself ? they do, however, evaporate over time.

Drying racks as well as work spaces still need to be ventilated and painters in lofts should not recirculate the same studio air in living and sleeping areas because a slow vapour build up could become toxic.
